Home-based music therapy - a systematic overview of settings and conditions for an innovative service in healthcare
Wolfgang Schmid, Thomas Ostermann
BMC Health Services Research , 2010, DOI: 10.1186/1472-6963-10-291
Abstract: The following databases were used to find articles on home-based music therapy: AMED, CAIRSS, EMBASE, MEDLINE, PsychINFO, and PSYNDEX. The search terms were "home-based music therapy" and "mobile music therapy". Included articles were analyzed with respect to participants as well as conditions and settings of HBMT. Furthermore, the date of publication, main outcomes, and the design and quality of the studies were investigated.A total of 20 international publications, 11 clinical studies and nine reports from practice, mainly from the United States (n = 8), were finally included in the qualitative synthesis. Six studies had a randomized controlled design and included a total of 507 patients. The vast majority of clients of HBMT are elderly patients living at home and people who need hospice and palliative care. Although settings were heterogeneous, music listening programs played a predominant role with the aim to reduce symptoms like depression and pain, or to improve quality of life and the relationship between patients and caregivers as primary endpoints.We were able to show that HBMT is an innovative service for future healthcare delivery. It fits with the changing healthcare system and its conditions but also meets the therapeutic needs of the increasing number of elderly and severely impaired people. Apart from music therapists, patients and their families HBMT is also interesting as a blueprint for home based care for other groups of caregivers.The use of music as a therapeutic option to support health dates back to ancient times. According to Bailey [1] some of the earliest notable mentions in Western history are found in the writings of ancient Greek philosophers Aristotle and Plato. In contemporary history, Michigan State University offered the first music therapy degree program worldwide in 1944. From that point, music therapy has established itself as a growing health profession for inpatients treatment of psychiatric diseases like schizophrenia or schizo
Lagrangian theory of structure formation in relativistic cosmology I: Lagrangian framework and definition of a nonperturbative approximation
Thomas Buchert,Matthias Ostermann
Physics , 2012, DOI: 10.1103/PhysRevD.86.023520
Abstract: In this first paper we present a Lagrangian framework for the description of structure formation in general relativity, restricting attention to irrotational dust matter. As an application we present a self-contained derivation of a general-relativistic analogue of Zel'dovich's approximation for the description of structure formation in cosmology, and compare it with previous suggestions in the literature. This approximation is then investigated: paraphrasing the derivation in the Newtonian framework we provide general-relativistic analogues of the basic system of equations for a single dynamical field variable and recall the first-order perturbation solution of these equations. We then define a general-relativistic analogue of Zel'dovich's approximation and investigate its implications by functionally evaluating relevant variables, and we address the singularity problem. We so obtain a possibly powerful model that, although constructed through extrapolation of a perturbative solution, can be used to put into practice nonperturbatively, e.g. problems of structure formation, backreaction problems, nonlinear properties of gravitational radiation, and light-propagation in realistic inhomogeneous universe models. With this model we also provide the key-building blocks for initializing a fully relativistic numerical simulation.
Quality of Life and Related Dimensions in Cancer Patients Treated with Mistletoe Extract (Iscador): A Meta-Analysis
Arndt Büssing,Christa Raak,Thomas Ostermann
Evidence-Based Complementary and Alternative Medicine , 2012, DOI: 10.1155/2012/219402
Abstract: Objectives. The aim of this meta-analysis was to determine the effectiveness of the fermented plant extract Iscador, produced from the white-berry European mistletoe, in the treatment of patients with cancer with respect to quality-of-life- (QoL-) associated measures. Methods. We searched databases such as PubMed/Medline, Excerpta Medica Database (EMBASE), CAMbase, and other for controlled clinical studies on parameters associated with QoL. Outcome data were extracted and converted into standardized mean differences and their standard errors. Results. Thirteen prospective and controlled studies which met the inclusion/exclusion criteria reported positive effects in favor of the Iscador application. A random-effect meta-analysis estimated the overall treatment effect at standardized mean difference =0.56 (CI: 0.41 to 0.71, <.0001). However, the methodological quality of the studies was poor. Conclusions. The analyzed studies give some evidence that Iscador treatment might have beneficial short-time effects on QoL-associated dimensions and psychosomatic self-regulation.
Survival of cancer patients treated with mistletoe extract (Iscador): a systematic literature review
Thomas Ostermann, Christa Raak, Arndt Büssing
BMC Cancer , 2009, DOI: 10.1186/1471-2407-9-451
Abstract: We searched several databases such as Cochrane, EMBASE, NCCAM, NLM, DIMDI, CAMbase, and Medline. Inclusion criteria were controlled clinical studies on parameters associated with survival in cancer patients treated with Iscador. Outcome data were extracted as they were given in the publication, and expressed as hazard ratios (HR), their logarithm, and the respective standard errors using standard formulas.We found 49 publications on the clinical effects of Iscador usage on survival of cancer patients which met our criteria. Among them, 41 studies and strata provided enough data to extract hazard ratios (HR) and their standard errors (Iscador versus no extra treatment). The majority of studies reported positive effects in favour of the Iscador application. Heterogeneity of study results was moderate (I2 = 38.3%, p < 0.0001). The funnel plots were considerably skewed, indicating a publication bias, a notion which is corroborated by statistical means (AC = -1.3, CI: -1.9 to -0.6, p <= 0.0001). A random effect meta-analysis estimated the overall hazard ratio at HR = 0.59 (CI: 0.53 to 0.66, p < 0.0001). Randomized studies showed less effects than non-randomized studies (ratio of HRs: 1.24, CI: 0.79 to 1.92, p = 0.35), and matched-pair studies gave significantly better results than others (ratio of HRs: 0.33; CI: 0.17 to 0.65, p = 0.0012).Pooled analysis of clinical studies suggests that adjuvant treatment of cancer patients with the mistletoe extract Iscador is associated with a better survival. Despite obvious limitations, and strong hints for a publication bias which limits the evidence found in this meta-analysis, one can not ignore the fact that studies with positive effects of VA-E on survival of cancer patients are accumulating. Future studies evaluating the effects of Iscador should focus on a transparent design and description of endpoints in order to provide greater insight into a treatment often being depreciated as ineffective, but highly valued by cancer pati
A pilot study on the effects of a team building process on the perception of work environment in an integrative hospital for neurological rehabilitation
Thomas Ostermann, Mathias Bertram, Arndt Büssing
BMC Complementary and Alternative Medicine , 2010, DOI: 10.1186/1472-6882-10-10
Abstract: Seventy seven staff members and 44 patients' relatives were asked to complete a survey that included the Work Environment Scale (WES-10), a Life Satisfaction Scale (BMLSS), the Conviction of Therapeutic Competency (CTC) scale and the Client Satisfaction Questionnaire (CSQ-8). To evaluate the outcome of the team building process, we analyzed changes over time in the WES-10 subscales. Additionally the interrelationship between the WES-10 subscales with other subscales and with sociodemographic parameters like age, gender was calculated by means of a bivariate correlation analysis.The team building process had a significant positive effect on perceived work environment in only one area. There was a significant improvement in the ward staffs' perception of their ability to constructively resolve conflicts 3 years after inception of the team building process than there was before inception. However, even in a unit that utilized holistic treatment and nursing in the care of severely disable patients, such care necessitating a very heavy workload, the measurements on the Self Realization, Life Satisfaction and Conviction of Therapeutic Competency scales remained high and unchanged over the three year time period of the study.Strategic interventions might be an option to improve interpersonal relationships and finally quality of patient care.The nature of the environment in which a medical staff does their work plays an important role in job satisfaction and performance. Several studies already investigated the relationship between the milieu in which health professionals work and the impact on job satisfaction. They proved that poor work environment is associated with reduced job satisfaction, absenteeism, somatic complaints, burnout and depression [1-3]. Moreover, poor work environment might also influence the work performance negatively, and might also promote negative and cynical attitudes towards patients and colleagues [4], which in turns will have an impact on the pa
Effects of music therapy in the treatment of children with delayed speech development - results of a pilot study
Wibke Gro?, Ulrike Linden, Thomas Ostermann
BMC Complementary and Alternative Medicine , 2010, DOI: 10.1186/1472-6882-10-39
Abstract: A total of 18 children aged 3.5 to 6 years with delayed speech development took part in this observational study in which music therapy and no treatment were compared to demonstrate effectiveness. Individual music therapy was provided on an outpatient basis. An ABAB reversal design with alternations between music therapy and no treatment with an interval of approximately eight weeks between the blocks was chosen. Before and after each study period, a speech development test, a non-verbal intelligence test for children, and music therapy assessment scales were used to evaluate the speech development of the children.Compared to the baseline, we found a positive development in the study group after receiving music therapy. Both phonological capacity and the children's understanding of speech increased under treatment, as well as their cognitive structures, action patterns, and level of intelligence. Throughout the study period, developmental age converged with their biological age. Ratings according to the Nordoff-Robbins scales showed clinically significant changes in the children, namely in the areas of client-therapist relationship and communication.This study suggests that music therapy may have a measurable effect on the speech development of children through the treatment's interactions with fundamental aspects of speech development, including the ability to form and maintain relationships and prosodic abilities. Thus, music therapy may provide a basic and supportive therapy for children with delayed speech development. Further studies should be conducted to investigate the mechanisms of these interactions in greater depth.The trial is registered in the German clinical trials register; Trial-No.: DRKS00000343Music therapy is an established form of creative art therapy. By using music as a specific medium of communication and expression and adapting it to the individual resources and abilities of the patient, music therapy can be beneficial in activating and suppo
Schulische und nicht-schulische Pr diktoren für die Studienplatzzusage an der Universit t Witten / Herdecke - Ergebnisse einer QUEST-Analyse [Academic and non-academic predictors for acceptance to medical studies at Witten/Herdecke University - findings of a QUEST-analysis]
Hofmann, Marzellus,Rieger, Monika A.,Ostermann, Thomas
GMS Zeitschrift für Medizinische Ausbildung , 2007,
Abstract: [english] Aims: Changes within the German Higher Education Framework act increasingly attract notice to the fact that the debate on different methods of selecting students lies in the responsibility of german medical schools. For more than 20 years the University of Witten/Herdecke has adhered to its own concept and procedure relating to its choice of students. Since 2005 this application procedure consists of a written and an oral application phase (assessment center). Within this study a retrospective classification of all applicants in the year 2005 was conducted, with the objective of finding academic and non-academic predictors for acceptance at Witten/Herdecke. Methods: All 172 applicants of the assessment center received a questionnaire asking for: age, gender, high school graduation mark, type of school, main school subjects, intended career, attendance at open house, parent graduation and profession. All duly completed questionnaires were classified according to the QUEST model from the viewpoint of acceptance versus refusal to medical studies at Witten/Herdecke. Outcomes: The QUEST model classifies the items of the questionnaire in sequence of declining power and in coherence to the targeted variable (acceptance). Affiliated with an increased probability of acceptance were: high school mark = 1.3, Steiner and Montessori schools, absence at open house, intended career as researcher and natural/social sciences and languages as main school subjects. Predictor sensitivity was 0.53, specificity reached 0.92. The positive predictive value accounted for 0.77, whereas the negative predictive value was 0.83. Conclusions: The high school graduation mark shows to be of high significance for the admission process at the University of Witten/Herdecke. Furthermore factors such as type of school, intended career and main school subjects play a major role. The high negative predictive value points out that the QUEST analysis is not suitable for replacing the existing admission process, but might be used for pre-selecting candidates. Further studies have to show whether the found effects are specific to the investigated group (applicants 2005) or whether they can be seen as representative for other cohorts of applicants at Witten/Herdecke. [german] Zielsetzung: Die Auseinandersetzung mit unterschiedlichen Verfahren der Studierendenauswahl rückt durch die Novellierung des Hochschulrahmengesetzes zunehmend in den Verantwortungsbereich deutscher Fakult ten. Als private Universit t führt die Universit t Witten/Herdecke (UWH) seit 20 Jahren universit tseigene Auswah
Selecting medical students at the University of Witten/Herdecke: Part I: Evaluation of inter-rater-reliability in the interview selection process

GMS Zeitschrift für Medizinische Ausbildung , 2005,
Abstract: Background: The University of Witten/Herdecke was founded in 1983 as the first private university in Germany to teach medicine. The University is not part of the centralized state system of medical placement distribution but rather has its own concept and procedure relating to its choice of students. In order to evaluate reliability and validity of the process of selecting medical students at the University of Witten/Herdecke, the first step was to analyse the interview selection process.Material and methods: The basic foundation of this examination were the results of the interview period of of the admission process from 1999 to 2000. In order to test inter-rater-reliability of the interviewers, a modified Cohen Kappa coefficient for multiple nominal scaled variables was used with regards to the group as a whole and also individually for the subgroups gender, admission year, age-groups and A Level results.Results: With Kappa-values ranging from 0.70 in 2000 to 0.88 in 1999 the reliability of the interviewer-process is obvious. However there are clear differences in the two years examined with regards to agreement in the decisions of interviewers. In the subgroup analysis with regards to gender no differences in the Kappa values were seen (male: 0,81; female: 0.8). Slightly less agreement can be seen with regards to subgroup analyses of A Level results of applicants ranging from 0.76 to 0.82.Discussion: In summary, this study shows that the application selection procedure for medicine at the medical faculty of the University of Witten/Herdecke is a reliable instrument with a high inter-rater reliability. This remains the case even though the interviewers do not seem to have standardized decision making criteria. Whether individual criteria/constellations were decisive with regards to the decision making process will be the subject of a further study.

Physics , 2013, DOI: 10.1093/mnras/stu1118
Abstract: As deeper galaxy catalogues are soon to come, it becomes even more importantto measure large-scale fluctuations in the catalogues with robust statistics that cover all moments of the galaxy distribution.In this paper we reinforce a direct analysis of galaxy data by employing the Germ-Grain method to calculate thefamily of Minkowski Functionals. We introduce a new code, suitable for the analysis of large data sets without smoothingand without the construction of excursion sets. We provide new tools to measure correlation properties, putting emphasis onexplicitly isolating non-Gaussian correlations with the help of integral-geometric relations. As a first application we present the analysis of large-scale fluctuations in the luminous red galaxy sample of Sloan Digital Sky Survey data release 7 data. We findsignificant deviations from the $\Lambda$ cold dark matter mock catalogues on samples as large as $500h^{-1}$Mpc (more than $3\sigma$)and slight deviations of around $2\sigma$ on $700h^{-1}$Mpc, and we investigate possible sources of these deviations.
Effects of Yoga Interventions on Fatigue: A Meta-Analysis
Katja Boehm,Thomas Ostermann,Stefania Milazzo,Arndt Büssing
Evidence-Based Complementary and Alternative Medicine , 2012, DOI: 10.1155/2012/124703
Abstract: Background. Researchers aimed at systematically reviewing and meta-analyzing the effectiveness of yoga interventions for fatigue. Methods. PubMed/Medline was searched until January 2012 for controlled clinical studies. Two reviewers independently extracted the data. The methodological quality of the studies was assessed. A meta-analysis was performed. Results. Nineteen clinical studies (total =948) were included in this review. Investigated yoga styles included Hatha, Iyengar, Asanas, Patanjali, Sahaja, and Tibetan yoga. Participants were suffering from cancer, multiple sclerosis, dialysis, chronic pancreatitis, fibromyalgia, asthma, or were healthy. Yoga had a small positive effect on fatigue (SMD = 0.27, 59% CI = 0.23–0.31). Seven studies received 4 points on the Jadad score. There were baseline differences in at least 5 studies. Conclusion. Overall, the effects of yoga interventions on fatigue were only small, particularly in cancer patients. Although yoga is generally a safe therapeutic intervention and effective to attenuate other health-related symptoms, this meta-analysis was not able to define the powerful effect of yoga on patients suffering from fatigue. Treatment effects of yoga could be improved in well-designed future studies. According to the GRADE recommendations assessing the overall quality of evidence, there is a moderate effect of the confidence placed in the estimates of the effects discussed here.
